Cables do transefer signals but what type of noise do they create or get rid of in the process? If he can't hear the difference then he can't hear well or he doesn't listen. My neighbors aren't audiophiles or videophiles but they can tell the difference easily in a demo on power cords with the plasma and the cdp. They are in amasement and one of them wants a shunyata power cord for his plasma now.
